An April 6 Huffington Post article summarized Professor of Music Murry Sidlin’s concert drama Defiant Requiem. PBS recently aired a documentary about the production, which tells the story of Jewish prisoners in the Theresienstadt Concentration Camp (also referred to as Terezín) near Prague during World War II who performed Verdi’s “Requiem Mass.”

If a hallmark of great art is its ability to transcend the limited circumstances of its creation, then there is no more heartbreaking realization of this than the 1944 performance of Giuseppe Verdi's Catholic Requiem by Jewish prisoners at the Nazi concentration camp Terezín. The story of Terezín and of the Requiem is told eloquently in director Doug Shultz's powerful new documentary Defiant Requiem, which premieres this Sunday, April 7, on PBS at 10 p.m. ET/PT (check listings for additional screenings on local PBS stations).
